GLASS-MOLD.

Specification of Letters Patent.

Patented Aug. 14, 1906.

Application filed March 24, .1905. Serial No. 251,775.

To (til wiwm it nmy concern: I Be,it known that I, WILLIAM KEENAN, acitizen of the United States, residing at To- -ledo, in the county ofLucas and State of l Ohio, have invented a new and useful Imware may beblown without mold-seams;

and a further objectis to adapt the mold for forming protuberances onthe face or into the i interior of the blown glassware.

The objects ofmy invention are accomplished as hereinafter described,and illusl trated in the drawings, in wl1ich- Figure 1 is a verticalsection, partly in elevation, of a mold constructed in accordance with.my invention.- Fig. 2 is a plan section on line X X of Fig. 1,showingthe mold filled and in position to be opened. Fig. 3 is an end elevationof the moldway. Fig. 4 is a tion in that the rotuberances are formed onplanview of mold in which the sections are inged together.

In Figs. 1 to 4, inclusive, the mold-section 1 is fixed to a bed-plate2, which is formed with ways 3 to movably receive thereon the base 4 ofthe opposite mold-section 5. link 6, coupled to this mold-section and toa lever 7,'p1voted to the bed-plate, furnish' means to move themold-section 5 against or away from the mold-section 1. The inner Wallsof the sections 1 and 5 are shaped as opposite semi'mold A of anydesired form and size and are adapted when the sections are broughttogether to jointly form a corn lite Y blowing aste-glass suspended froma pipe against t e wall of the mold. In order to form protuberance onthe inner wall of the glassware, the mold is provided with a pluralityof studs 8,- each arranged in line with the separation of themold-sections, and to permit twirling of the glassware to avoidmold-joint seams the studs 8 are mounted to ring-sections 9 and 10,which are revolubly let in and held in a dovetailed annular recess 1 1,formed continuous through both sections.

The ring-section 9 is provided with, a stud 12, arranged to indicatethrough a slot 13in the mold-section 1 when the parting-lineo of' thering-sections 9 and 10 is coincident with the parting-line of the mold,in which coincident position only the parting of the mold-sections ispossible. A portion .14 of the recess 11 is extended in line with theindicator-stud to form a free path for the same when'the ringsectionsare revolved. The bed-plate 2 is also rovided with a circular recess 15,into whic 1 a plate 16 is inserted to form a revoluble mold-bottom,facilitating twirling of the glassware to avoid the mold-jointsappearing therein.

In Fig. 4 the mold-sections 1 and 5 are rovided with ring-sections 17and 18, eac i of which is provided with a plurality of recesses 19,adapted to form protuberanccs on the face of the glassware, saidrecesses being also arranged to permit the glassware, with theprotuberanccs, to be freely withdrawn when the mold-sections areseparated the required distance.

In Fig. 5 the mold-sections 1 and 5 are provided with hinges 20,permitting them to swing open, and may be provided with either theringsections 9 and 10 or ring-sections 17 and 18.

One of the mold-sections is preferably pro vided with do rel-pins 21,ads. ted to enter coincident apertures 22, tonne in the oppo sitesection to assure alinement of the dovetail recess 11 when thescctionsare brought together for forming the mold.

In the manufacture of glassware having a perforated section those moldsare particuarly useful in that the rotuberances may be easily removedafter (I leased from the mold and producing thereby glassware having novisible seam other than in the perforated section.

What I claim is- In a glass-mold comprising partible moldsections,having an annular recess formed continuous through the sections, a ringrevolubly mounted in the annular recess, partiblc with the moldsectionsand having means for forming (protuberances on the blown glasswa l'g ana revoluble bottom-plate for the -mo i In witness whereof I havehereunto si ned my name, in the presence of two subscr'liing witnesses,this22d day of March, 1905.

- WILLIAM KEENAN.
